Abstract
The invention discloses an extrusion forming device for composite casting of semi-solid metal slurry and liquid metal melt. The extrusion forming device comprises a base. A support is vertically arranged on the base. The upper end of the support is fixedly connected with an extrusion rod. One end of a pull rod is hinged and connected to the top end of the support. The pull rod is connected with a steel wire rope through a lifting lug. The lower end of the steel wire rope is fixedly connected with the two side ends of an extrusion cylinder. The lower end of the extrusion cylinder is provided with an opening. A shearing platform is arranged on the inner wall of the opening, and the extrusion cylinder is suspended in a crucible. When the pull rod is upwards lifted, the steel wire rope can drive the extrusion cylinder to move upwards so that the extrusion rod can enter the extrusion cylinder. The invention aims at providing the extrusion forming device for composite casting of the semi-solid metal slurry and the liquid metal melt, and the problems that an interface formed through liquid/liquid combining is poor in width regulation and control performance, and oxide skin is prone to being mixed or left in interfaces formed through solid/solid combining, solid/liquid combining, semi-solid/solid combining and semi-solid/semi-solid combining processes are solved.
Description
Technical field
The present invention relates to the extrusion forming device of metal material processing Technology field, a kind of semi-solid metal slurry and melted metal composite casting.
Background technology
The research of double metallic composite material, the history of the best decades, Gu its preparation is combined from solid/compound, solid-liquid, it is combined to liquid liquid, arrive semisolid/solid union etc. again, derive miscellaneous combination process, but its essence only one of which: obtain continuous-stable, the combination interface of high intensity.The combination interface of continuous-stable and high intensity is extremely important for the actual application of double metallic composite material, is also to prepare high-performance, the premise of multipurpose double metallic composite material and basis.The solid complex technique of metallurgical bonding interface have solid/compound, liquid/solid is compound, liquid liquid is compound, semisolid/solid union and semisolid/semi-solid bonding etc., but they respectively have deficiency in terms of the preparation of double metallic composite material.If utilizing liquid liquid to be combined technology and the equipment preparing double metallic composite material, rely on semi-solid metal slurry characteristic, solid be expected to solve that the interface width control that is compounded to form of liquid liquid is poor and solid/compound, solid-liquid is combined, the interface of semisolid/solid union and semisolid/semi-solid bonding technique formation is easily mingled with or the problem such as residual oxidization skin.
Summary of the invention
It is an object of the invention to provide the extrusion forming device of a kind of semi-solid metal slurry and melted metal composite casting, solid solve interface width control difference that liquid liquid is compounded to form and solid/compound, solid-liquid is compound, the interface of semisolid/solid union and semisolid/semi-solid bonding technique formation is easily mingled with or the problem such as residual oxidization skin.
For solving above-mentioned technical problem, the present invention adopts the following technical scheme that
A kind of semi-solid metal slurry and the extrusion forming device of melted metal composite casting, including base, it is vertically installed with support on described base, described pedestal upper end is fixedly connected with pressure ram, and described cantilever tip is articulated and connected pull bar one end, and described pull bar passes through hanger connecting steel wire ropes, the two side ends connecting recipient is fixed in described steel wire rope lower end, the lower end of described recipient is opening, and described opening inwall is provided with shearing platform, and described recipient is unsettled to be arranged in crucible；When being lifted up described pull bar, described steel wire rope can drive described recipient to move upward to make described pressure ram enter in described recipient.
Further, the lower end of described pressure ram is positioned at described recipient upper end.
Further, described recipient two side ends is provided with and mates fixing connection ring with steel wire rope.
Further, totally 2, described steel wire rope, one end of two described steel wire ropes connects recipient one side, and the other end connects described recipient another side relative to position after both passing through the through hole on described hanger.
Compared with prior art, the Advantageous Effects of the present invention: realized the preparation of high performance bimetallic covered composite yarn ingot casting by semi-solid metal slurry/melted metal composite casting technology, solid solve interface width control difference that liquid liquid is compounded to form and solid/compound, solid-liquid is compound, the interface of semisolid/solid union and semisolid/semi-solid bonding technique formation is easily mingled with or the problem such as residual oxidization skin, it is thus achieved that faying face is stable, non-scale or be mingled with and composite that intensity is high；And by compound tense use pull-up to make starting point that internal layer semi-solid metal slurry is squeezed out in the bottom of crucible, thus solve because semi-solid metal slurry that density is little cannot enter the difficult point of the big melted metal core of density by self gravitation from the top of crucible.
